Health issues and touring commitments have combined to postpone Aerosmith’s next album, according to guitarist Joe Perry.

Record sessions… were delayed when he had to have surgery earlier this year to clear out an infection in his knee replacement.

Aerosmith’s tour, the group’s first since 2007, starts in June with ZZ Top. Perry says about 40 dates are set so far for North America, with South America, Europe and Japan also under consideration. The itinerary should be announced soon.
